Key Issues for the World Biofuels Market Alfred Szwarc Hart's World Refining & Fuels Conference: Americas Rio de Janeiro August 2, 2006
Content Specifications Harmonization Increase in Productivity Ethanol from Cellulose Tax Barriers
Ethanol Biobased Synthetic Fuel Ethanol Industrial Beverage Hydrous Anhydrous Proprietary Grades Denaturated Undenaturated
Anhydrous Fuel Ethanol Ethyl Alcohol with very low water content, generally derived from biomass (sugar cane, sugar beet, corn, wheat, barley, cellulose feedstocks etc.), denaturated or not. It is blended to gasoline. The product has many specifications!

Worldwide Fuel Charter refers to oxygenates recommends ethers (???) Ethanol (up to 10%) shall comply to ASTM D4806 (only???) No mention of neat ethanol use or in FFVs No consideration for Brazilian extensive experience
New York Board of Trade NYBOT Biomassderived (does not specify feedstock), undenatured, anhydrous ethanol at 60 degrees Fahrenheit. Chicago Board of Trade CBOT* Chicago Mercantile Exchange CME Cornderived* in compliance with ASTM D4806 + California requirements
Hydrous Fuel Ethanol Used as a neat fuel and (as in Brazil) used in FFVs Also has many specifications and suffers from the same lack of harmonization
Harmonization Issues Grade type classification Main specifications should be common Production process may require additional specifications (starch X sugar feedstocks) Units Stakeholders ( ethanol producers, auto industry, fuel distributors, governments, traders, consumers, environmental groups) WTO, ISO etc
Harmonization Benefits Standard key specifications Easier quality assurance Product certification & traceability standardization Lower costs Wider product acceptance Key for international market growth Key for turning fuel ethanol into an energy commodity In line with globalisation trends
Increase in Productivity Existing production processes are being continuously improved increasing production yields and reducing energy consumption Post2010 Source: IEA, 2005

Ethanol from Cellulose Still at research and demonstration level: many countries at advanced stage Foreseeable commercial production: 5 15 years Will represent a revolution in supply possibilities (agriculture, forestry & industrial residues, municipal garbage etc) Existing ethanol producers may boost significantly production lower costs
Tax Barriers I BioEthanol is being considered a strategic alternative in terms of: energy diversity and security sustainability (renewable fuel) mitigation of the Greenhouse Effect mitigation of urban air pollution reduction of foreign debt (oildependent countries that may become producers) jobs generation development of new technologies
Tax Barriers II BioEthanol is still being viewed as a byproduct Import taxes inhibit the development of a competitive international market: USA: 2.5% ad valorem + US$ 0.54/gallon EU: 192/m 3 (undenaturated) and 102/m 3 (denaturated) Japan: 27.2% ad valorem 10%
Concluding Remarks Harmonization of specifications is key for the development and growth of biofuels markets Discussion of harmonization needs and benefits is necessary and requires an international effort Productivity of conventional processes is increasing and additional production from cellulose will boost ethanol use Tax barriers are incompatible with today s need for biofuels market development and should be lifted or considerably reduced
